Yes, you will notice the missing 333 mhz
I had this happen to me. I thought it was odd that I was maxing the processor so frequently, and that the 500-megahertz TiBook seemed almost as fast as the miniBook.
The page above suggests that a PRAM reset (Command-Option-P-R on startup) will straighten everything out, but that wasn't enough on my PowerBook. I had to also reset the Power Management Unit: With the machine off, press and release Shift-Control-Option-Power On at the same time. Nothing will happen, but wait at least 5 seconds. Power up, and check that you're back to normal.
You can verify that you're fixed with Xbench, or with the shell command 'sysctl hw.cpufrequency'.

I posted this tip to the Mac users group mailing list at UW and it helped a couple of people. There were some concerns that 10.2.8 was not QA-ed at all, with Panther right around the corner. Dunno about that, but then I'm not a laptop user, the group most affected by this. My angst might be more keen if I were.
